Abstract
The utility model discloses a kind of door and window trolley, comprise metal pulley body, on the outer circumferential surface of pulley body, be provided with the annular groove matching with guide rail, in pulley body, offer axially extending bore, in axially extending bore, be equipped with bearing, in pulley body, be symmetrically arranged with two annular slots, pulley body, bearing and two annular slots coaxially arrange, in two annular slots, inlay card has a hole back-up ring respectively, hole is greater than the aperture of axially extending bore with the external diameter of back-up ring, two holes offset with the two sides of bearing respectively with back-up ring.The load-bearing of the utility model door and window trolley is large, long service life, can be applicable to the load-bearing of various bars, is specially adapted to the load-bearing of large weight bar, also can be applicable to the occasion of the larger load-bearing of the various needs such as household, factory.
Description
Technical field
The utility model relates to a kind of Hardware fitting that is applied to translation door and window, specifically a kind of door and window trolley.
Background technology
Existing parallel-moving type door and window generally comprises bar and doorframe and window frame, pulley is installed on bar, one-body molded on doorframe and window frame have the guide groove or the guide rail that match with pulley, pulley plays load-bearing and guide effect to bar, the moving around of the bar of scrolling realization back and forth on guide groove or guide rail by pulley when use.Pulley is made of plastics mostly, its load-bearing is inadequate, easy to wear, after wearing and tearing, can cause bar to sink, impact is used, especially be not suitable for the load-bearing of large weight bar, doorframe and window frame is generally aluminium or plastic-steel in addition, and pulley contacts the frictional heat producing with aluminium or plastic-steel easily makes pulley produce distortion, affects pulley application life.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provide that a kind of load-bearing is large, the door and window trolley of long service life.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of door and window trolley, comprise metal pulley body, on the outer circumferential surface of described pulley body, be provided with the annular groove matching with guide rail, in described pulley body, offer axially extending bore, in described axially extending bore, be equipped with bearing, in described pulley body, be symmetrically arranged with two annular slots, described pulley body, bearing and two annular slots coaxially arrange, in annular slot described in two, inlay card has a hole back-up ring respectively, described hole is greater than the aperture of described axially extending bore with the external diameter of back-up ring, hole described in two offsets with the two sides of described bearing respectively with back-up ring.
As preferably, described bearing is 629 serial bearings.The internal diameter of 629 serial bearings is 9mm, and external diameter is 26mm, and thickness is 8mm, belongs to deep groove ball bearing, and radially weight capacity is stronger, and friction factor is little, and vibration and noise are little, and precision is high, is first-selected bearing type.In actual applications, according to the weight size of carried bar, can required kinds of bearings and the model of choose reasonable.
More preferably, described bearing is 629Z bearing.The sealing of 629Z bearing in 629 serial bearings (as NSK 629Z bearing, SKF 629Z bearing, etc.) is moderate, and price is lower.
Compared with prior art, the utility model has the advantage of: the door and window trolley that the utility model provides comprises metal pulley body, and weight capacity is strong, good heat resistance, not yielding after long-term use; In pulley body, offer axially extending bore, in axially extending bore, be equipped with bearing, in pulley body, be symmetrically arranged with two annular slots, in two annular slots, inlay card has a hole back-up ring respectively, bearing is clamped with back-up ring by two holes, bearing is played to the effect of axial limiting, prevent from causing that because bearing rocks pulley double swerve affects the use of door and window.The load-bearing of the utility model door and window trolley is large, long service life, can be applicable to the load-bearing of various bars, as various bearing doors, push, move window etc., be specially adapted to the load-bearing of large weight bar, also can be applicable to the passing frame that the various carryings such as household, factory are larger.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment door and window trolley;
Fig. 2 is the elevation of embodiment door and window trolley.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in the figure, a kind of door and window trolley, comprise the pulley body 1 that brass is made, on the outer circumferential surface of pulley body 1, be provided with the annular groove 11 matching with guide rail (not shown), in pulley body 1, offer axially extending bore 12, in axially extending bore 12, be equipped with 629Z bearing 2, in pulley body 1, be symmetrically arranged with two annular slots 13, pulley body 1, bearing 2 and two annular slots 13 coaxially arrange, two interior inlay cards respectively of annular slot 13 have a Ф 26 back-up ring 3 for hole, hole is greater than the aperture of axially extending bore 12 with the external diameter of back-up ring 3, two holes offset with the two sides of bearing 2 respectively with back-up ring 3.
